Instead of helping patients who are suffering from their illnesses, a hospital worker planned to kill them.

A hospital worker, who worked with dialysis patients, was accused of asking them to give him their pain killers. He is now behind bars after allegedly pouring bleach into the dialysis machines at the clinic.

Foster Donald III, 49, who worked at the clinic of Fresenius Medical Care in West Columbia, South Carolina, was arrested after a month-long investigation by local authorities.

The clinic workers discovered the contaminated solutions before anyone was injured.

He has been charged with attempted murder and burglary in the second degree. He is currently being held on bail of $525,000.
Foster was suspended from his job as a technical equipment coach on July 2, but returned less than a week later. That is when he contaminated the solutions, police said.

"He had planned to carry out mass murder to avenge his employer," said Lexington County Sheriff James Metts.
Foster poured bleach in the tank containing the purified water used to filter waste from the bodies of 20 patients, hoping the deaths caused by his sabotage would bankrupt the company, police said.

The 49-year-old single father asked a judge to let him out of jail because he has to take care of his 5-year-old daughter.
